Does anyone have any knowledge of using epsom salts as a spray on greenhouse tomato plants? The bottom leaves on my plants are curling, with brown mottling, before turning yellow - I'm told it's either a watering problem or magnesium deficiency. I don't know which.
I have watered in Epsom salts a week ago, but with no effect. If I spray it on the leaves, am I likely to cause other problems?
As for the rain and slugs... I've tried to be good but the slug damage has been horrendous, and I had to bite the bullet. All my susceptible plants and veg now have a liberal carpet of slug pellets around them. Works a treat!
